To what extent do you think IQ actually plays a role? Surely some (or all, don't really know the exact stats) professional chess players have high IQ, but it could be correlation rather than causation.
With the recent development in technology, unfortunately chess has really become more about pattern recognition, memorisation and correct engine use for prep. Not saying that creativity is completely out of the picture now, but it surely has less space. As for intelligence it only plays a role for the time it takes for you to understand a concept imo, i.e. someone more intelligent could understand the ideas behind a certain rook ending faster than someone who less.
So everything said above aside, are there more factors that come into play? Probably, and plenty of them at that, because humans are complex. So even if the numbers of the 2 sides become equal, would you ensure that all the other factors are also equal, thus proving that gender is the limiting factor?
It is known that in IQ and other mental tests, men have more outliers than women. That means that men are more likely to be on the extremely high or extremely low end of the spectrum, and women more densely populate the middle.
Professional chess players are outliers, by definition. If the above hypothesis is also true by chess, it would follow that since men have more outliers, they would also have more professional chess players. With more professional chess players, they would also be more likely to produce the world champion.
This theory is often called misogynistic. However, this is a scientific argument, not based on any contempt or bias. Misogyny is not a valid claim here. Men and women have other advantages and disadvantages, and that’s what makes both of them unique and special. (Additionally, this would mean that less women would be horrible at chess.)
If this is true, it would support women’s titles as a permanent measure, not just a temporary tool to attract more women to the game. It would also support separate women’s tournaments and a separate women’s world championship being held indefinitely.
I think the likelihood of this hypothesis being true is high. Although women can certainly gain ground by introducing more to the game, I think they will eventually plateau at a slightly lower level than men.
What do you think?
